In Japan, the rural sewerage projects are being actively carried out. On the other hand, it is afraid that we are running short of water. Thinking of the rural sewerage treatment, we can understand that the construction of sewage plant is the construction of recycling plant of water in a sense. The sludge is always produced as the results of purification of sewage in the plant. But, the sludge is hated as dangerous and troublesome matters by people. In the old time, night soil was used by farmer for agriculture. But, as the chemical fertilizers are being produced, human manure is disliked and is not paid attention to. Therefore, it leads to environmental problems in many places. Reviewing agricultural field, as supply of organic matter to agricultural fields was stopped and only the chemical fertilizer were used, the field has lost the fertility. Then we started the study to reuse the purified wastewater to solve the shortage of water, and to use the composted sludge as organic fertilizer to enrich soil. It is concluded from our study that (1) the purified wastewater can be recycled as irrigation water equivalent to drinking water, (2) the composted sludge used and valued high as organic fertilizer. It is not to say that the exact check has to be done if both of the recycled water and sludge meet the environmental standard or not before their reusing.

在日本，农村污水处理工程正在积极开展。另一方面，又担心我们缺水。思考农村污水处理，我们可以理解污水厂的建设在某种意义上就是水循环利用厂的建设。污泥总是作为工厂污水净化的结果产生的。但是，污泥却被人们视为危险和麻烦的物质而憎恶。在古代，粪便被农民用于农业。但是，随着化肥的生产，人类粪便不再受到人们的喜爱，也没有受到重视。因此，导致很多地方出现环境问题。回顾农业领域，由于停止向农田供应有机质，仅使用化肥，土地失去了肥力。然后我们开始研究将净化后的废水回用以解决水资源短缺问题，并将堆肥污泥用作有机肥来肥沃土壤。我们的研究得出的结论是：（1）净化后的废水可以回收作为相当于饮用水的灌溉水，（2）堆肥污泥可以作为有机肥料使用并具有很高的价值。这并不是说再生水和污泥在回用前必须严格检查是否符合环保标准。
